pyGNMI: Python gNMI client

This repository contains pure Python implementation of the gNMI client to interact with the network functions.

Usage

Sample code example:

# Modules
from pygnmi.client import gNMIclient

# Variables
host = ('169.254.255.64', '57400')

# Body
if __name__ == '__main__':
    with gNMIclient(target=host, username='admin', password='admin', insecure=True) as gc:
         result = gc.get(path=['openconfig-interfaces:interfaces', 'openconfig-acl:acl'])

    print(result)

Also integration with Nornir is supported (refer to examples).

Dev Log

Release 0.3.12:

• Minor bug fix.

Release 0.3.11:

• Minor bug fix.

Release 0.3.10:

• Renamed the debug mode. Add argument debug=True upon object creation to see the Protobuf messages.

Release 0.3.9:

• Added functionality to list the full the device configuration in case the path is empty: get(path[]).

Release 0.3.8:

• Merged the proposal how to implement TLS with override for Cisco IOS XR (tested for Cisco IOS XR, to be tested for other vendors yet)

• Merged examples with TLS

Release 0.3.7:

• Added the argument encoding as an extra key to Set operation

Release 0.3.6:

• Added the argument encoding to Get operation

Release 0.3.5:

• Added the example for Nornir Integration

• Added the topology diagram

• Added links to the video tutorial

Release 0.3.4:

• Added the close method to gNMIClient class for those, who doesn’t use with ... as ... context manager.

Release 0.3.3:

• Added the functionality to pass gRPC messages to the code execution

Release 0.3.2:

• Minor bugs fixed.

Release 0.3.1:

• Minor bugs fixed.

• Added examples of gNMI operations.

Release 0.3.0:

• Added new function telemetryParser, which converts Protobuf messages in Python dictionary.

• Fixed the errors with the telemetry parsing.

Release 0.2.7:

• Modified core so that telemetry is working in once and stream mode.

Release 0.2.6:

• Added alpha version of the Subscribe operation.

Release 0.2.5:

• Added typing hints.

Release 0.2.4:

• Minor bugfixing.

Release 0.2.3:

• Added support for IPv6 transport (now you can connect to the network function over IPv6).

Release 0.2.2:

• Added conversion of the collected information over the gNMI into a Python dictionary for Set operation.

Release 0.2.1:

• Fixing the bugs with improper Protobuf paths generation.

• Now all Set operations (delete, replace, and update) are working properly.

Releast 0.2.0:

• Added the Set operation from gNMI specification.

Releast 0.1.9:

• Added the property datatype='all' to the get() request. The values are per the gNMI specification: all, config, state, operatonal.

Release 0.1.8:

• Added conversion of the collected information over the gNMI into a Python dictionary for Get operation.

Release 0.1.7:

• Changing packages modules.

Release 0.1.6:

• Restructuring internal context.

Release 0.1.5:

• Minor bugfixing.

Release 0.1.4:

• Minor bugfixing.

Release 0.1.3:

• Minor bugfixing.

Release 0.1.2:

• The gNMIClient is recreated as context manger.

• Tests with Nokia SR OS done, the module is working nice for insecure channel.

Release 0.1.1:

• Added the Get operation out of gNMI specification.

Release 0.1.0:

• The first release.
